Grommet having an identifying portion for checking the grommet

Abstract

A grommet 11 includes a vehicle body mount portion 11a to be mounted on a panel of a vehicle body and a wire insertion portion 11b to be mounted on a wiring harness. A checking projection 11c is formed in a desired position on an outer surface of the vehicle body mount portion 11b of the grommet. The grommet 11 may be used with a checking device 10 formed with a grommet receptacle 10b and a checking recess 10e in which the checking projection 11c is to be fitted for checking whether the grommet is of a specified shape.

What is claimed is: 
     
       1. A grommet for sealed passage of a wire harness through a hole in a panel, said grommet having opposed first and second ends and comprising: a substantially tubular wire insertion portion (11b) extending from the first end of the grommet to a location between said first and second ends;   a tapered mount portion (11a) having a small diameter end at said wire insertion portion (11b) and a large diameter end between the wire insertion portion (11b) and the second end of the grommet, said large diameter end of said mount portion (11a) defining an outside diameter for sealed engagement with the panel at the hole therethrough;   an annular rim (11f) extending from the large diameter end of the tapered mount portion (11a) to the second end of the grommet and having an outer circumferential surface disposed radially outwardly from the large diameter end of the tapered mount portion (11a), the annular rim (11f) including a diametrically disposed support rib (11g) extending thereacross; and   at least one identifying portion (11c) formed on and projecting from the rib (11g) and protecting substantially perpendicular to said rib (11g) and away from said first end.   
     
     
       2. A grommet according to claim 1, wherein the wire insertion portion (11b) is concentrically defined around a longitudinal axis, the at least one identifying portion (11c) extends substantially parallel to the longitudinal axis of the wire insertion portion (11b). 
     
     
       3. A grommet for sealed passage of a wire harness through a hole in a panel, said grommet having opposed first and second ends and comprising: a substantially tubular wire insertion portion (11b) extending from the first end of the grommet to a location between said first and second ends;   a tapered mount portion (11a) having a small diameter end at said wire insertion portion (11b) and a large diameter end between the wire insertion portion (11b) and the second end of the grommet, said large diameter end of said mount portion (11a) defining an outside diameter for sealed engagement with the panel at the hole therethrough;   an annular rim (11f) extending from the large diameter end of the tapered mount portion (11a) to the second end of the grommet and having an outer circumferential surface disposed radially outwardly from the large diameter end of the tapered mount portion (11a); and   at least one identifying portion (11c) formed on and projecting from the rim (11f), the identifying portion being a planar flange (11h) of polygonal shape disposed at the second end of the grommet (11) and extending outwardly from the rim (11f).
